Everything We Think We Know About the Apple iWatch

2014: the year of the wearable? From Google's Glass to Android Wear and all manner of fitness trackers in between, mobile devices will be slithering out of the primordial soup that's splashing around in your pocket, and most will be making their way onto your wrist.

Rumours of an Apple iWatch predate this latest wearables craze by years. With Apple's tablet line established, the iPhone facing stiff competition and iOS 8 looking to extend Apple's health credentials, the stage finally seems set for the entrance of the iWatch. With the rumour mill churning, here's everything we think we know so far about Apple's tech-heavy timepiece.

What to Expect From the iWatch Specsheet

Sensors, sensors, sensors. It will come as no surprise, but Apple's smartwatch will be less concerned with telling you the time than telling you precise details about the workings of your body. It's going to be all about health and fitness monitoring, as suggested by the focus placed on those sectors during the iOS 8 reveal. 10 sensors in all are said to feature in the device, and many of those will be biometric: one is rumoured to measure hydration by analysing your sweat, another would help weightlifters track repetitions, another would keep the beat with your heart. There's even been talk of a barometer tucked away inside.

In more general hardware terms, everything from a 1.3-inch to a 2.5-inch display has been suggested, along with wireless charging capabilities. Apple Insider points towards a 200 to 250mAh battery being included, while the NYT suggests battery power could also be supplemented by kinetic or solar power.

What Will the iWatch Software Do?

Though supply chain leaks can give us a rough idea of what the hardware may look like, the software side of things is more like guesswork. Though Apple is expected to have full (yet tailored) iOS 8 on the iWatch, it's in lockdown — don't expect to see any software leaks until the iWatch enters production, if ever before release.

But, given rival smartwatch capabilities, the rumoured sensors onboard and a few extrapolations from the iOS 8 reveal, we can make a few educated guesses.

First, the obvious stuff. Linked up to an iPhone (likely over Bluetooth), it would be outrageous if the iWatch didn't offer some sort of customisable notifications system, alerting the wearer of incoming message and calls, perhaps even letting you answer directly from the watch using the iOS / OS X ecosystem's new Continuity and Handoff features. Paired up with Apple's new HomeKit API, iWatch apps could be central to an Apple home automation system — even if that proves to be less fully-featured than some Jetsons wannabes would hope for.

But it's the health and fitness monitoring stuff that seems Apple's main focus, built with a level of depth that would set it apart from the competition. iOS 8's Health app will feature in some form on the iWatch, with the wearable device likely providing much of the data that the app relies upon through the wristwatch sensors. There's the potential here for everything from blood sugar level to heart problems to be monitored, alongside standard fitness and wellbeing metrics such as steps taken and how settled a sleeping session has been. In the US at least it seems Apple ultimately wants to partner with health practitioners, letting them remotely monitor patient data from the iWatch, taking the strain off overstretched medical staff.

What Will the iWatch Look Like?

It will be interesting to see how Apple translates its iOS 8 operating system into a form that's digestible on a smaller wearable device. Arguably, iOS 7's push towards a flatter, cleaner look for the operating system paved the way for the iWatch's tailored version of iOS — the last thing you want on a tiny screen is busy skeuomorphic designs. Google's Android Wear interface is a good jumping off point if you're at a loss as to what to expect from a wearable UI.

The hardware design is a little easier to predict — you're relatively certain to get either a circular touchscreen display or a square one. Or maybe Apple will offer both — it's been suggested that two different iWatch models will launch, one with a rectangular screen and rubber strap aimed at sports enthusiasts, along with a circular "Designer" model sporting a stainless steel link band. Talk of a curved touchscreen display has quietened down recently, but given how lovely Samsung's Gear Fit looked (even if it didn't perform that well in use) Apple may consider following suit. Expect to see sapphire glass protecting that display too.

Regardless, there have been plenty of concept designs from enthusiastic Apple fans knocking around to give some indication as to what an iWatch may look like. Here are a few of the best:

When Will the iWatch Release and Go on Sale?

Seeing as it's going to be so reliant upon a connected iPhone device, it's a safe bet to imagine that the iWatch will be launched alongside the iPhone 6. According to the latest rumours, the smartphone is set to arrive in either late August or (more likely) early September. It's standard timing for the Cupertino company, allowing Apple to build a buzz around the devices just in time for the Christmas present buying rush.

Deutsche Telekom has suggested that September 19th will be the exact date that the iPhone 6 will hit stores, and its possible that the iWatch would land alongside it. However, reliable Apple analyst John Paczowski is reporting that the iWatch will land in October. Either Apple is giving the iPhone 6 some retail breathing space in that case, or both may slip back to the later month.

How Much Will the iWatch Cost?

Now that's a good question. Apple's gear always carries a premium, so it's tough to even gauge against the the pricing of Google's first wave of Android Wear devices (the LG G Watch costs $249).

Morgan Stanley analyst Katy Huberty predicts that the iWatch could rake in as much as $17.5 billion for Apple during its first 12 months on sale, at a selling price of $299. Directly converted, that price tag would be over $300 in Australia. But for Apple, that seems low. Expect to see it selling closer to the $400 mark.
